Acer Sole Undercut Irons (Available in Right or Left Hand) feature an undercut channel embedded within a thick mass area near the sole to create optimal trajectory at impact. Dual powerpads provide mass at the high toe and heel areas to compensate for mis-hits. A cambered sole and rounded toe add to the forgiving nature of this club. An excellent all-around club for any level of golfer. Compare performance to Callaway's HawkeyeŽ.
